CLEANER FOR FLouR-BoLTs.

SPECIFICATION forming part of Letters Patent No. 571,41 1, dated November 17, 1896, Application ned January 7, 1896. serai No. 574,585. (No moda.)

To all whom, it may concern.-

Beit known that I, FRANK R. STTTZEL, a citizen of the United States, residing at Loudonville, in the county of.Ashland and State of Ohio, have invented a new and useful Cleaner for Flour-Bolts, of which the following is a specification. i

In bolting and reeling flour great annoyance is 'occasioned by the vchoking and clogging of the reels, especially if the flour is damp, and to obviate this difficulty brushes and. other cleaning devices have been devised and result more or less injuriously to `the cloth of the reel or bolt by coming and remaining in frictional engagement therewith.

This invention aims. to provide a cleaner which will jar the cloth of the reel by striking the same a smart and light blow at intervals, thereby dislodging the particles of flour lodging in the meshes of the cloth and keeping the reel clean and free without wearing the same, as is the case with brushes.

Other objects and advantages are contemplated and will become apparent as the nature of the improvement is better understood, and to a full understanding of the merits reference is to be had to the accompanying draw-1 bolt and attached either to the latter or to its ings and the following description.

The improvement is susceptible of various chan ges in the form,proportion,and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a perspective view of a :Hour-bolt of ordinary construction, showing the invention in operative relation thereto. Fig. 2 is a detail view of the knocker and its actuating mechanism. Fig. 3 is a detail section of the cam and its supporting-ratchet. Fig. 4 is a detail view of the cam disconnected from its support. Fig. 5 shows a different way of constructing and mounting the cam. Fig. 6 is a transverse section on the line X X of Fig. 5.

Like numerals of reference denote similar and corresponding parts in all the figures of the drawings.

The invention is intended to be applied to bolts and reels for treating ground cereals of any nature, and is illustrated in connection with a flour-bolt 1 of ordinary construction and mounting. The knocker consists of a bar 2, either of wood or metal and of sufficient mass to tap or strike the flour-bolt lightly, so as to dislodge the particles from the meshes of the cloth without injuring the latter. As shown, the knocker or bar 2 is supported by arms 3, which are pivoted at their outer ends to pins 4., extending inwardly from the sides of the framework 5 of the flour-bolt. These pins 4 have annular grooves near their outer ends, and the ends of the arms 3 are bent so as to t into the said annular grooves, thereby preventing any appreciable longitudinal movement of the knocker in its vibratory movements. A tappet 6 is adjustably connected with the knocker and projects into the path of a cam 7, by which it is operatedto actuate the knocker, so as to attain the desired end. This tappet is formed with a longitudinal slotv 8, and a bolt 9, passing through the slot S. serves to connect the tappet with the knocker in the located and adjusted position.

A shaft 10 extends approximately parallel with' the fiour-bolt, and is provided at one end with a Ypinion 11, which meshes with a gearwheel 12,constructed to revolve with the iioursupporting shaft or journal. By this means the shaft 10 is caused to rotate with the Hourbolt, and the cam 7, mounted thereon, engaging with the tappet, operates the knocker to cause it to strike the bolt smartly, so as to clear the same of the particles tending to clog or choke its meshes.

The cam is mounted upon the shaft 10 in such a manner as to prevent breakage of the parts in the event of the motion of the liourbolt or the shaft 10 being reversed, and as illustrated a ratchet-wheel 13 is secured upon the shaft l0, and is formed with a hub portion 14, upon which is loosely mounted the cam `7, the latter being confined between the ratchetwheel 13 and a disk 15, mounted upon the end portion of the hub, and which latter has its extremity upset, so as to retain the disk l5 in proper position. A pawl 16 is pivoted to a side of the cam and its free end engages with the teeth of the ratchet-wheel 13, and a spring 17, secured to the cam, engages with the pawl and maintains the latter in operative relation with the ratchet-wheel. The

ICO

frictional engagement of the cam with its mountings is sufficient to maintain the parts4 in working relation and to cause the cam. to rotate with the shaft 10, so as to actuate the knocker, since the latter is very light and requires the expenditure of a small amount of force to properly operate it.A In the eventv of the four-bolt or the shaft 10 rotating in a reverse direction the shoulder 18 of the cam 7 will engage with the tappet 61, and the ratchet-wheel 13 will turn with the shaft l0 and its teeth will ride under the pawl 16, thereby allowing thecam to. remain stationary without straining or breakin g any of the parts.

The length of the shoulder 1S represents, practically, the lift of the cam, and the active portion of the latter gradually recedes from the outer end of the shoulder 18y to the b ase thereof. Hence the moment the tappet is released from the outer end of the cam it is engaged by the latter and is gradually lifted, thereby elevating the knocker to a position to be again dropped upon the bolt to strike the latter a blow suflicient to dislodge the particles of flour adhering` in its meshes. Byadjusting the tappet. 6 so as to project to a greateror less extent from the knocker the throw of' the latter can be regulated, as will be. readily comprehended.

As shown i-nFi-gs. 5 and 6, the oa1n19 is formed in one side with av recess 2,0, the edge of which is provided with ratchetteeth 21, and a collar 22, secured tothe shaft 10 by binding-screw 23, is supplied with pawls 24 to en gage with the teeth 21, so as to cause the cam, collar, and shaft to move together clockwise, but admitting of the shaft 10 turningbackward without injuring the parts. A col lar 25 is secured upon the shaft 10, and the cam Itis @onli-ned between the collars 22 and 25. with the teeth 2l by springs 2t', and the parts 21, 24 and 26 are housed and protected by the walls inclosing the recess 20, within which thc parts are located.

l-lavingthus described the invention, what is claimed as new is- Th-epawls 24 are held in engagement 1. The combination with a Hour bolt or reel,

` of a knocker to strike the same smartly, and

an actuating-cam mounted upon a shaft to set forth for the purpose described.

2. The combin ation with a flour bolt or reel, of a pivotally-supported knocker to strike the l same. smartly, a tappet adjustably connected with the knocker, and an actuating-cam to engage with the tappet for operating the i knockerand mounted upon a shaft to rotate therewith i-n one direction and to remain stationary upon the turning of the shaft in an opposite direction, substantially as set forth.

3. The combination with a flour bolt or reel,

j of a knocker for strikingy the sidesv` thereof, a shaft, a ratchet-wheel secureduponthe shaft,A

a cam mounted upon' the ratchet-wheel and adapted to engage with and operate the knocker, and a pawl carried by the cam and f adapted to engage with the teeth of the ratclr I eti-wheel,` substantially as and for the purpose.

4g. The combination with a flour bolt or reel 0f' a knockenarms secured at one end to the knocker and pivotally supported atV their op,- :posite end,l a tappet having adjustable conwith the teeth. ofthe ratchet-wheel, substantially as and; for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto afIiXed my signature in the presence of two witnesses.
